Using an efficiency model, it is shown that reduced tissue Nconcentration and reduced root maintenance respiration, both of which are predicted to result from elevated CO2, should lead to slightly longer root life spans.
MARKED DIFFERENCES IN SURVIVORSHIP AMONG APPLE ROOTS OF DIFFERENT DIAMETERS

This work used minirhizotron data from 16-yr-old apple (Malus domestica) trees to investigate differences in life span and life history among fine roots whose diameters differed by tenths of a millimeter, and advocated the use of a functional definition for the fine root whenever possible.

Comparisons showed that peach has not undergone recent whole-genome duplication, and even though the ancestral triplicated blocks in peach are fragmentary compared to those in grape, all seven paleosets of paralogs from the putative paleoancestor are detectable.
Changes in the risk of fine-root mortality with age: a case study in peach, Prunus persica (Rosaceae).

Baseline hazard function plots revealed that the timing of high-risk periods was generally related to seasonal factors rather than individual root age, and this effect was largely due to different rates of mortality among roots of different orders, diameters, and depths.

The increasingly widespread use of minirhizotrons, below-ground video cameras, and root image analysis software has generated information on fine root dynamics in many species and ecosystems, but a number of studies indicate that roots of different ages and positions are anatomically and physiologically dissimilar.

Most Type I genes appear to have arisen through tandem duplications after the divergence of the Arabidopsis and peach lineages, whereas Type II genes seem to have increased following whole genome duplication events, and phylogenetic and expression data suggest that individual orthologs may not function identically across all species.
Genotyping by Sequencing for SNP-Based Linkage Map Construction and QTL Analysis of Chilling Requirement and Bloom Date in Peach [Prunus persica (L.) Batsch]

The Genotyping-By-Sequencing (GBS) method developed for cereals is applied to the discovery of single nucleotide polymorphisms (SNPs) in a peach F2 mapping population, a genetic and genomic model within the Rosaceae and will provide a template for the use of this method with other members of this family.

Minirhizotrons provide detailed information on the production, life history and mortality of fine roots. However, manual processing of minirhizotron images is time-consuming, limiting the number and…
Soil insects alter fine root demography in peach (Prunus persica)

- 1 March 2002
It is suggested that interactions with below-ground insects can significantly influence root longevity and may alter the rate at which roots undergo developmental changes in anatomy and physiology.
